Communication Apparatus, Communication Method, and Communication System

1. An electronic device comprising circuitry configured to: receive a wireless coordination signal to set up a coordination link in a first frequency band; transmit a report frame via the coordination link, the report frame indicating capabilities of a second frequency band; perform wireless communication in the second frequency band with another electronic device, the second frequency band being higher than the first frequency band; and perform a Request to Send (RTS)/Clear to Send (CTS) procedure over the second frequency band with the another electronic device.

2. The electronic device of claim 1 , wherein the RTS/CTS procedure is initiated during a priority use period allocated to the electronic device according to scheduling information received in the first frequency band.

3. The electronic device of claim 1 , wherein a center frequency ratio of the second frequency band to the first frequency band is at least 12:1.

4. The electronic device of claim 1 , wherein: the first frequency band is centered at approximately 5 GHz, and the second frequency band is centered at approximately 60 GHz.

5. The electronic device of claim 2 , wherein a third communication station performs wireless communication with a fourth communication station in the second frequency band also in accordance with the scheduling information.

6. A communication apparatus comprising: a first analog unit including one or more antennas; a second analog unit including two or more antennas; circuitry configured to: receive a wireless coordination signal to set up a coordination link in a first frequency band via the first analog unit; transmit a report frame via the coordination link, the report frame indicating capabilities of a second frequency band; perform wireless communication in the second frequency band with another electronic device via the second analog unit, the second frequency band being higher than the first frequency band; and perform a Request to Send (RTS)/Clear to Send (CTS) procedure over the second frequency band with the another electronic device.
